2 Claims.

This invention relates to hose nozzles; and it has more particularreference to nozzles for the drain hoses of vehicles such as areordinarily used in the delivery of gasoline, oils and other 5 liquidcommodities.

The filling openings of underground gasoline storage tanks of roadservice stations vary considerably in diameter so that tips of differentsizes are ordinarily supplied for use with the nozzles on the hoses ofthe delivery vehicles. heretofore, reducing nipples were relied upon asa means for effecting interchange of the nozzle tips; and accordinglythe operation of interchanging the nipples was not only tedious in itsaccomplishment, but entailed the use of wrenches or other special tools.In order to avoid this effort and trouble, the drivers of the deliveryvehicleswould invariably keep the smallest nozzle nipple .as a permanentfixture on the hose since it could be used universally, and this choicewas made notwithstanding great loss in time in charging tanks whereofthe filling openingswere capable of taking larger or even full sizenozzles.

Considered from the broadest aspect, my invention is directed towardovercoming the above recited drawbacks, that is to say: it has for itsprimary object the provision of a simple and inexpensive nozzle for thedrain hoses of gasoline delivery vehicles and the like, with tips whichcan be interchanged with the utmost facility and quickness, and withoutrequiring the aid of any tools whatever.

An advantage of my novel hose nozzle is that it positively ensures quickattachment and detachment of the nozzle tips by partial rotation of oneof the parts only.

Other objects and attendant advantages of this invention will bemanifest from the following detailed description of the accompanyingdrawing wherein Fig. I is a fragmentary view partly in side elevationand partly in section showing my improved hose nozzle in one of theformsin which it may be embodied.

Fig. II shows a nozzle tip. having a tubular discharge prolongation of asmaller diameter, capable of being interchanged with the nozzle tipshown in association with the nozzle in Fig. I;

Fig. III is a staggered horizontal section taken as indicated by thearrows III-III in Fig. I.

Fig. IV is a fragmentary sectional view of a portion of Fig. I with theparts difierently positioned; and,

Fig. V is a view similar to Fig. III with the parts differentlypositioned.

Referring first to the embodiment of my in- 933, Serial No. 678,619 (or.zss- -ss) vention shown in Figs. I-V of these illustrations, the numeralll designates a flexible hose such as is used on vehicles employed-inthe delivery of gasoline, oils and other liquid commodities, the samebeing fitted at its end wit fathreaded nipple l2. My improved hose no'zzl'e' which is comprehensively indicated at I3 comprises a body memberin the form of an elbow H which, as shown in Fig. I, screws onto thethreaded nipple l2 with interposition of a compressible ring washer 15to prevent leakage-around the juncture. The mouth end of the elbow I3 isenlarged as at l6 and formed internally wi th a circumferential grooveIT for lodgment of the peripheral flange of an annular gasket I8. Inpractice, this gasket [8 is made from a soft resilient material which isresistive' to erosion by the liquid commodities being carried.The'"e'n1arged mouth end [B of the body member I4 is circumferentiallyrecessed at l9; and a flanged annulus 20 screwed onto said mouth endforms, in conjunction with the recess IS, a perimetric groove aroundsaid mouth. Rotatably retained within this perimetric groove is a wedgering 2|, which, as shown in Fig. III, is formed internally'thereof witha circumferential series of recesses 22 having cam slopes or inclines23. The wall of the mouth end IQ of the elbow I4 is moreover formed 7with radial openings 24 corresponding in number to the recesses 22 inthe wedge ring 2|, each such opening lodging a ball 25. As shown in Fig.III, the openings 24 are tapered to retain the balls 25 while limitinginward radial movement thereof.

For interchangeable use with the body member H of the nozzle I provide anumber of-tips whereof there are two shown for the purposes ofexemplification in the present instance, one designated 21 in Fig. I andanother designated 21a in Fig. II, the nozzle 21a differing from thenozzle 21 in that it has a tubular prolongation 28a which is smaller indiameter than the tubular prolongation 28 of said nozzle 21, and also ina detail which will be later described. Referring again to Fig. I itwill be observed that the nozzle tip 21 has a head 29 which iscounterbored as at 30 to receive the prolongation 28, the latter beingin practice cut from tubing of alloy bronze or other suitablenon-corrosive metal capable of withstanding rough usage. Afterassembling of the parts of the tip 21, they are permanently securedtogether by soldering or welding preferably at 3| immediately beneaththe head 29, which latter is provided with a rounded circumferentialgroove 33. The diameter of the bore 84 of the'tubular prolongation 2| 0!the nozzle tip 21, it will be'observed, corresponds exactly to thediameter of the passage 85 in the elbow It, so that the maximumdischarge how is bad with said tip.

The head 28a 0! the substitutable noule tip 11a has an external diametercorresponding to that of the tip 21 so as to fit, like the latter, intothe mouth It of the nozzle elbow i4, and it is similarly provided with acircumferential groove 33a; The head Ila or the nozzle tip 21 is howeverrounded interiorly at I. for smooth mergence o! the bore Ila oi .theprolongation Ila with the passage 3! oi the elbow I4 and minimization ofthe impedance to fluid fiow throughthenomle. Y

In attachingthe nozzle tipll, for example, -the wedge ring is turned tothe position shown in my, to register its'recesses. 12, with theopenings 24 in the wall of the elbow mouth itandtopermittheballsfltoretire into said recesses. Thereupon, the headend 2l oi the tip 21 is inserted into' the elbow mouth It as shown inFig. IV until'its endrahuts the gasket It, the allocation of thecircumferential groove- 33 of said head being such that in this position0! the tip 2I, the groove are slightly below the level of the radialopenings 24 in the wall of the elbow enlarged mouth end I. Withthenozzle tip 21 placedas Just explained, thewedgeringilisturnedclockwisaorasindicated y the arrow in Fig. V, to theposition shown in BI, with the result that by action of the inclines orslopes 23 or the recesses", the balls Ilarethrustinwardottheopeningsuinthe wail-ioivthe elbow I4 and forced into the circumferential groove33 of the head 2! of the no'zle tip 21.; As a consequence of theattendant wedginga'ctionbetweentheballsllandthe groove 33, the tip-21will'be lifted until said balls and groove are in exactalisnmentverticaily, .as in Fig.1, with attendant'compression o! theresilient gasket ll to form a fluid-tight seal between thenozz'le parts,and with concurrent lockingtogether of saidparts. In

order to limit the extent or rotation of the" wedge ring II the latteris provided, as shown in 'l'l'gs. I, III, lv and V with a pair 01'spaced upward lugs 31, 38 for cooperation with a lateralstud nozzle ll.

From the foregoing it will be seen that the interchangeable nozzle tipsare quickly attachable and detachable through a partial rotation of onepart relative to the other.
